MATTRESS-FRAME.

Specification of Letters Patent.

Patented Jan. 2, 1917.

Application filed July 13, 1914. Serial No. 850,561.

To all whom it may concern:

Be it known that I, FRANCIS G. GALE, a subject of the King of Great Britain, residing at l/Vaterville, Province of Quebec, Dominion of Canada, have invented an Improvement in Mattress-Frames, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to bed bottoms and has for its object to provide a novel construction by which the bed bottom is stiffened and prevented from warping or racking and by which the fabric can be tightened if it begins to sag after use.

In order to give an understanding of the invention I have illustrated herein a selected embodiment thereof which will now be described, after which the novel features will be pointed out in the appended claims.

In the drawings Figure 1 is a view partly in section of one corner of the bed bottom; Fig. 2 is a section on substantially the line m00, Fig. 1.

I have not deemed it necessary to illustrate herein a complete bed bottom, but have shown the construction at one corner only, it being understood that this construction is duplicated at the other corners thereof.

1 is the side rail of the bed bottom or mattress frame.

2 represents thewirc fabric which is connected by means of springs 3 with the end rail 4.

Each side rail 1 is provided at each end with a riser or head 5 to which the end rail is secured.

My invention aims to provide a novel construction for connecting the end rail 1 to the risers 5 which not only enables the fabric 2 to be adjusted to take up any slack or sag therein, but which also prevents the mattress frame from twisting or warping as iron frames frequently do.

Each riser 5 is provided with a flat supporting surface 6 on which the end rail 4 rests, said end rail having an angle-iron shape. Said end rail is provided at each end with a guiding and stiffening member 7 also having an angle-iron shape, the vertical leg 8 of which sets inside of and is rigidly secured to the vertical leg 9 of the end rail 4 by suitable means, such as rivets l0, and the horizontal leg 11 of which rests on the supporting surface 6. Each of these guiding members 7 is provided with a guiding stud 12 which extends through a slot 13 formed in the portion 6 of the riser 5. These guiding pins 12 are preferably in the form of bolts having heads 120 which rest on the horizontal leg 11 of the stiffening member 7, said bolts having screw-threaded thereto nuts 14 which engage the underside of the portion 6 of the risers and serve to keep the stiffening members 7 in proper position. Each riser 5 is also provided with a vertically-extending flange 15 through which loosely passes an adjusting bolt 16 that extends through the vertical legs 8 and 9 of the angle-iron members 7 and 41, respectively, and has screw-threaded engagement with a nut 17 which rests against the inner face of the leg 8. This nut will be non-circular and is of a size to fit between the head 120 of the bolt 12 and the horizontal leg of the angle-iron 1, said nut being held from turning by its engagement with these parts.

By means of this construction the bed bottom fabric 2 can be tightened by simply turning the bolts 16, the slots 13 providing for the adjusting movement of the end rail 4:. The presence of the guiding and stiffening members 7 at the ends of the end rail serves to hold the latter in proper position on the portions 6 of the risers 5 and prevent the frame from warping or becoming twisted. The supporting surfaces 6 of the risers are comparatively wide and furnish a firm support for the horizontal legs 11 of the guiding members 7.

The construction above described is simple, inexpensive and provides a rigid mattress frame.

I claim:

1. In a mattress frame, the combination with side rails having risers at their ends, each provided with a flat supporting surface and an upturned flange at the outer end of said surface, of an angle-iron end rail to which the bed bottom fabric is connected, an angle-iron stiffening and guiding member secured to each end of the end rail and having its vertical leg overlying the vertical leg of the end rail and its horizontal leg resting on the supporting surface, the portion of each riser on which the guiding member rests being provided with a slot, a bolt extending through the horizontal legs of each guiding member and operating in the slot in the riser, an adjusting bolt extending through the vertical flange of the riser and the vertical legs of the end rail and guiding member, and a nut on the inner face of said guiding member which is held from turning by contact with the head of the first-named bolt.

2. In a mattress frame, the combination with side rails having risers at their ends, each provided with a flat supporting surface and an upturned flange at its outer end, of an end rail to which the bed bottom fabric is connected, a guiding member securedto each end of the end rail and resting on the supporting surface, the portion of each riser on which a guiding member rests being provided with a slot a bolt eX- tending through the guiding member and operating in said slot, arr adjusting bolt extending through the vertical flange of the riser and through the end rail, and a nut on the inner end of said adjusting bolt which engages the .head of the first-named bolt.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing Witnesses.
